820 goes into 4373 5 times with a remainder of 273.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 4100 from 4373 and we're left with 273.
Bring next digit (6) of the dividend behind the 273 and repeat the process: 2736 / 820

Step 5:
If we divide 2736 by 820, we get 3 and a remainder of 276.
Write down 3 as next digit of the result. 
Result so far: 53.0
If we subtract 2460 from 2736, we get 276.
Take the next digit (9) from the dividend and append it to 276, then repeat: 2769 / 820

Advancing to step 6:
820 goes into 2769 3 times with a remainder of 309.
Put 3 as the next digit of the answer. 
Result so far: 533.0
The remainder is 309 after subtracting 2460 from 2769.
Fetch the next digit (9) from the dividend, attach it to 309 and continue: 3099 / 820

Step 7:
3099 divided by 820 is 3 with a remainder of 639.
Write down 3 as next digit of the result. 
Result so far: 5333.0
If we subtract 2460 from 3099, we get 639.
Append the next digit (4) from the dividend to 639 and continue with: 6394 / 820

Going ahead to step 8:
820 can be fit into 6394 7 times, resulting in a remainder of 654.
The next digit of our result is 7. 
Result so far: 53337.0
Subtract 5740 from 6394 to get 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Advancing to step 9:
If we divide 6540 by 820, we get 7 and a remainder of 800.
Record the quotient 7 as the next digit in the result. 
Result so far: 53337.7
Subtracting 5740 from 6540 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 10:
8000 divided by 820 is 9 with a remainder of 620.
Record the quotient 9 as the next digit in the result. 
Result so far: 53337.79
The remainder is 620 after subtracting 7380 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 11:
If we divide 6200 by 820, we get 7 and a remainder of 460.
Write down 7 as next digit of the result. 
Result so far: 53337.797
The remainder is 460 after subtracting 5740 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 12:
When dividing 4600 by 820, we get 5 with a remainder of 500.
The next digit of our result is 5. 
Result so far: 53337.7975
Deduct 4100 from 4600 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 13:
When dividing 5000 by 820, we get 6 with a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 53337.79756
Subtracting 4920 from 5000 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
820 goes into 800 0 times with a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 53337.79756
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Moving on to step 15:
820 goes into 8000 9 times with a remainder of 620.
The number 9 becomes the next digit in our result. 
Result so far: 53337.7975609
If we take 7380 away from 8000, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 16:
The number 820 fits into 6200 7 times, leaving a remainder of 460.
Use 7 as the next digit of our solution. 
Result so far: 53337.79756097
Subtract 5740 from 6200 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final outcome is 53337.79756097, with a leftover of 4.6e-07.
